The US Antitrust System and Recent Trends in Antitrust Enforcement
综述了美国反垄断体系，包括司法部和联邦贸易委员会的角色，并通过计量分析发现反垄断执法具有趋势性、与商业周期联动，且政府诉讼领先私人诉讼。
This paper provides a survey of recent research on the US antitrust system. First we provide an overview of the US antitrust system, describing the roles of the US Department of Justice, the Federal Trade Commission and case law. Second, we provide a new econometric trend analysis on the enforcement of US antitrust law, showing that (1) enforcement demonstrates some trend behavior, as well as comovement with business cycles; (2) the time series of antitrust cases demonstrates two distinct episodes, which we characterize as ‘pre‐deregulation’ and ‘post‐deregulation;’ (3) the time series of government antitrust filings leads the time series of private antitrust filings. Finally, we describe recent economic research relevant to the area of antitrust and the impact of this research on US antitrust policy.
